Part 30 Demolition

Section 419 Disconnecting services

All electric, gas, water, steam, sewer, and other services lines should be disconnected i.e. shut off, capped, or otherwise controlled, at or outside the structure before demolition begins. In each case, any utility company which is involved should be notified in advance, and its approval or services, if necessary, should be obtained. Written confirmation of the disconnection is required. This written confirmation should be readily available at the work site to workers and an officer.

If it is necessary to maintain any power, water, or other utilities during demolition, such lines should be temporarily relocated as necessary and/or protected. The location of all overhead power sources should also be determined, as they can be especially hazardous during any machine demolition. All workers should be informed of the location of any existing or relocated utility service.
